Description

Technical Field

[0001] The invention belongs to the field of photocatalytic treatment, and in particular relates to photocatalytic water treatment equipment. Background Art

[0002] Although photocatalytic water treatment technology has environmental advantages, its practical application has long been limited. The main reasons include: the contradiction between light transmittance and fouling: the thickness of the water layer needs to be strictly controlled (too thick will block light), but a thin water layer tends to accelerate scaling on the catalyst surface, and traditional technologies cannot take both into account. Catalyst activity decay: biofilm or inorganic precipitation covers the active sites of the catalyst, and manual cleaning is costly and interrupts operation. Equipment efficiency bottleneck: the water flow path of the single-stage reactor is short, and the degradation of pollutants is not complete; ultraviolet lamps are only used for disinfection, and their photocatalytic potential is not fully utilized. Therefore, a photocatalytic water treatment device is proposed. Summary of the Invention

[0003] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0004] In view of the following technical problems in the existing technology: Dirt accumulation on the catalyst surface: During long-term operation, biofilm or sediment is easily formed on the catalyst surface, blocking light penetration and significantly reducing the photocatalytic efficiency;

[0005] The thickness of the water layer affects light transmittance: an excessively thick water layer will absorb or scatter ultraviolet light, weakening the light's excitation effect on the catalyst and resulting in decreased degradation efficiency; low equipment space utilization: traditional devices make insufficient use of the reaction chamber space, resulting in short water residence time and insufficient contact between pollutants and catalysts; high energy consumption and maintenance costs: the outer wall of traditional UV lamps is prone to scaling and difficult to clean, requiring frequent maintenance.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: a photocatalytic water treatment device, comprising a treatment cylinder, a treatment chamber is provided inside the treatment cylinder, and a light treatment mechanism, a stirring mechanism, a transmission mechanism and a catalytic mechanism are provided inside the treatment chamber;

[0007] An input pipe is provided at the top of the processing chamber, and an exhaust pipe is provided at the bottom of the processing chamber.

A vacuum cylindrical cavity is provided in the inner cavity of the transparent tube, a central column is provided in the middle of the vacuum cylindrical cavity, and several light release components are evenly arranged around the periphery of the central column.

[0008] As a preferred technical solution for photocatalytic water treatment equipment, the light release component includes a reflective arc plate and an ultraviolet lamp tube. Several reflective arc plates are evenly arranged on the periphery of the central column, the ultraviolet lamp tube is arranged in the middle of the reflective arc plate, and the inner side wall of the reflective arc plate is provided with a reflective coating;

[0011] As a preferred technical solution for photocatalytic water treatment equipment, the stirring mechanism includes a rotating table, a transmission frame, a vertical column, a horizontal plate and a stirring plate. The rotating table is connected to the transmission mechanism. Three transmission frames are evenly arranged on the rotating table. The ends of the transmission frames away from the rotating table are fixedly connected to the vertical columns. The top and bottom of the vertical columns are provided with horizontal plates. Several stirring plates are provided between the two horizontal plates.

[0012] The rotating table rotates slowly through the vertical column, the horizontal plate and the stirring plate, and stirs the water in the processing chamber through the stirring mechanism.

[0013] As a preferred technical solution of a photocatalytic water treatment device, a connecting arc plate is provided between two adjacent vertical columns, and the number of the connecting arc plates is three.

[0014] As a preferred technical solution of a photocatalytic water treatment device, a servo motor is provided at the bottom end of the treatment cylinder, and the bottom end of the central column is fixedly connected to the power output end of the servo motor.

[0015] As an optimal technical solution for a photocatalytic water treatment device, a transmission mechanism includes a processing table, a support rod, an inner gear ring, gear 1, a movable chamber, gear 2 and gear 3. A movable chamber is provided on the inner side of the bottom of the processing table, and the inner gear ring is rotatably connected in the movable chamber. The inner circumferential wall of the inner gear ring is provided with transmission teeth. Gear 1 meshes with the inner wall of the inner gear ring.

One side of the processing table is fixedly connected to the inner bottom wall of the processing chamber through the support rod. Gear 2 and gear 3 are rotatably connected inside the processing table. Gear 2 and gear 3 mesh with each other. Gear 2 is connected to the inner gear ring and is coaxial. The upper side of gear 3 is fixedly connected to the rotating table through a transmission shaft.

[0016] The center column drives gear 1 to rotate, and gear 1 is decelerated through the inner ring gear, that is, the speed is reduced. The inner ring gear drives gear 2 to rotate, and gear 2 drives gear 3 to rotate slowly in the opposite direction. Gear 3 drives the turntable to rotate slowly in the opposite direction. The turntable slowly reverses through the vertical column, horizontal plate and stirring plate, and the water in the treatment chamber is stirred by the stirring mechanism.

[0017] As a preferred technical solution of a photocatalytic water treatment device, the bottom end of the rotating table is rotatably connected to a rolling wheel, and the rolling wheel is movably connected to the upper side of the treatment table;

[0018] The rolling wheels carry the rotating table.

[0019] As a preferred technical solution of a photocatalytic water treatment device, the vertical column is provided with a plurality of attachment seats, each of which is in the shape of a triangular prism and is located on the side of the stirring plate facing the center of the treatment chamber;

[0020] The attachment seat is provided with a plurality of attachment grooves, and the inner walls of the attachment grooves are provided with catalyst particles;

[0021] The attachment seat is located on the side of the stirring plate facing the center of the processing chamber, so that the ultraviolet lamp can irradiate the catalyst particles and generate active free radicals through catalysis for disinfection.

The light treatment mechanism includes a transparent cylinder, a central column, and a light release assembly. The transparent cylinder cavity is provided with a vacuum cylindrical cavity, the vacuum cylindrical cavity is provided with a central column in the middle, and several light release assemblies are evenly arranged around the central column. Efficient dirt removal and anti-blocking: Through the counter-rotating rotation of the stirring mechanism and the light release assembly, combined with the physical wiping of the cleaning brush, the friction generated by the continuous rotation of the stirring mechanism and the water flow automatically removes deposits on the catalyst surface and maintains light transmittance.

[0023] The catalyst particles on the attachment seat are washed by the rotation of the stirring plate and the water flow, reducing the adhesion of dirt.

[0024] To optimize light utilization and mixing efficiency, the elliptical inner wall of the reflective arc plate focuses the UV light and evenly disperses it around the processing chamber, expanding the irradiation range.

[0025] The stirring mechanism rotates in the opposite direction to the light source, which enhances the turbulence of the water flow, allows the pollutants to fully contact with the catalyst, and improves the uniformity of degradation.

[0026] Compact structure and efficient use of space

[0027] The stacked design (such as tower plates and flip screens) increases the effective reaction area and reduces the equipment footprint; the weir plate controls the thickness of the liquid layer and balances the transmittance and reaction time.

[0048] The rotating platform 18 rotates slowly in reverse through the vertical column 4 , the horizontal plate 5 and the stirring plate 7 , and stirs the water in the processing chamber 2 through the stirring mechanism.

[0049] A connecting arc plate 3 is provided between two adjacent vertical columns 4 , and the number of the connecting arc plates 3 is three.

[0050] A servo motor 12 is provided at the bottom end of the processing cylinder 1 , and the bottom end of the central column 11 is fixedly connected to the power output end of the servo motor 12 .

[0051] The transmission mechanism includes a processing table 16, a support rod 20, an inner ring gear 13, a gear 14, an active chamber 15, a gear 2 17 and a gear 3 19. The active chamber 15 is provided on the inner side of the bottom of the processing table 16. The inner ring gear 13 is rotatably connected in the active chamber 15. The inner circumferential wall of the inner ring gear 13 is provided with transmission teeth. Gear 1 14 meshes with the inner wall of the inner ring gear 13. Gear 1 14 is connected to the center column 11 through a transmission shaft. The processing table 16 is provided at the top of the processing chamber 2. One side of the processing table 16 is fixedly connected to the inner bottom wall of the processing chamber 2 through the support rod 20. The interior of the processing table 16 is rotatably connected with gear 2 17 and gear 3 19. Gear 2 17 and gear 3 19 mesh. Gear 2 17 is connected to the inner ring gear 13 and is coaxial. The upper side of gear 3 19 is fixedly connected to the rotating table 18 through a transmission shaft.

[0052] The center column 11 rotates with gear 1 14, and gear 1 14 is decelerated through the inner ring gear 13, that is, the speed is reduced. The inner ring gear 13 rotates with gear 2 17, and gear 2 17 rotates with gear 3 19 in the opposite direction at a slow speed. Gear 3 19 rotates with the turntable 18 in the opposite direction at a slow speed. The turntable 18 slowly reverses through the vertical column 4, the horizontal plate 5 and the stirring plate 7, and the water in the processing chamber 2 is stirred by the stirring mechanism.

[0053] The bottom end of the rotating platform 18 is rotatably connected to a rolling wheel, which is movably connected to the upper side of the processing platform 16;

[0054] The rolling wheels carry the rotating platform 18 .

[0055] The vertical column 4 is provided with a plurality of attachment seats 8, each of which is in the shape of a triangular column and is located on the side of the stirring plate 7 facing the center of the processing chamber 2;

[0056] The attachment seat 8 is provided with a plurality of attachment grooves 23, and the inner walls of the attachment grooves 23 are provided with catalyst particles;

[0057] The attachment seat 8 is located on the side of the stirring plate 7 facing the center of the processing chamber 2, so that the ultraviolet lamp 26 can irradiate the catalyst particles and generate active free radicals through catalysis for disinfection.

[0058] The catalytic mechanism includes an attachment seat 8 .

[0059] Several pushing plates 27 are evenly arranged on the outside of the annular cleaning frame 9, and the cleaning brush 24 contacts the outer peripheral surface of the transparent cylinder 10. Several rotating rods 28 are arranged on the inside of the annular cleaning frame 9, and two track grooves 29 are arranged on the outside of the transparent cylinder 10. The rotating rods 28 extend into the track grooves 29. During the rotation of the stirring plate 7, a forward or reverse vortex water flow will be generated. The vortex water flow itself can not only clean the outside of the transparent cylinder 10, but also push the annular cleaning frame 9 to rotate through the pushing plates 27. The annular cleaning frame 9 rotates with the rotating rods 28 and the cleaning brush 24. During the rotation of the cleaning brush 24, the outer peripheral surface of the transparent cylinder 10 is scrubbed, and the rotating rods 28 move along the groove path of the track groove 29, thereby causing the annular cleaning frame 9 to rise or fall.

[0060] The inner side wall of the reflective arc plate 25 is elliptical, and the ultraviolet lamp tube 26 is the focus of the ellipse.

[0061] The ultraviolet lamp 26 generates ultraviolet light, and the reflective arc plate 25 gathers the light and radiates it from the middle of the treatment chamber 2 to the surrounding areas. The ultraviolet light irradiates the catalytic particles on the attachment seat 8 and catalytically disinfects the water.

[0063] The catalyst particles include nano-titanium dioxide.

[0064] The specific implementation method is as follows: water is injected into the processing chamber 2 through the input pipe 21, the servo motor 12 controls the rotation of the central column 11, the central column 11 drives the gear 1 14 to rotate, the gear 1 14 is decelerated by the inner ring gear 13, that is, the speed is reduced, the inner ring gear 13 drives the gear 2 17 to rotate, the gear 2 17 drives the gear 3 19 to rotate slowly in the opposite direction, the rotating table 18 rotates slowly in the opposite direction, and the rotating table 18 slowly reverses through the vertical column 4, the horizontal plate 5 and the stirring plate 7, and the water in the processing chamber 2 is stirred by the stirring mechanism;

[0065] The stirring mechanism rotates in the opposite direction to the light-releasing component, and the relative position of the light-releasing component and the attachment seat 8 is constantly changing, so that all parts of the water liquid are evenly irradiated and catalyzed to produce a two-stage reaction design to increase the concentration of active free radicals, enhance the ability to oxidize pollutants, and shorten the treatment cycle. The active free radicals include hydroxyl radicals.

[0066] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
